1 Claim. (Cl. 16-115) My invention relates generally to storm windowsand specifically to triple track storm windows having disappearinghandles.

It is among the object's of my invention to provide a storm windowconstruction in Which handles for lowering the Window are included.

It is a further objectofr'ny invention to provide a storm windowconstruction in which handles for lowering the window disappear andappear automatically.

It is yet a further object of my invention to provide a storm windowconstruction in which handles for lowering the window do not interferewith the close placement of the storm window with respect to other stormwindows in a double or triple track construction.

It is yet a further object of my invention to provide a storm windowconstruction in which the handles for lowering the window are pleasingin appearance and unobtrusive.

Yet a further object of my invention is to provide a storm windowconstruction in which the handles for lowering the window are simple toconstruct, durable and relatively inexpensive.

These objects and advantages, as Well as other objects and advantages,may be achieved by the device illustrated in the drawings in which:

Figure 1 is a front elevational view of a storm window partially raised;

Figure 2 is a cross-sectional view taken on the line 2-2 in Figure 1;

Figure 3 is a front elevational view of the window shown in Figure 1lowered into contact with the window sill; and

Figure 4 is a front elevational view of the tab.

Referring now to the drawings in detail, which are merely illustrativeof one embodiment of my invention, my storm window construction presentsthe conventional storm window in which the top, bottom and pair ofopposite sides are formed of extruded aluminum strips 11. Each of thesealuminum strips is usually provided with an inside channel 12 and anoutside channel 13. A pane of glass 14. is usually fitted into the topchannel 12 with an intervening cushion strip 15 serving to cushion'theglass in the channel and to formulate an air-tight seal by reason of itscompressibility. The outside channel 13 of such strip 11 serves toreceive the rails 16 at the side of the window upon which the sash runsas it is raised and lowered.

in constructing storm windows (which are primarily desirable because oftheir heat insulating properties) it has been found desirable to placethese windows as closely as possible to the permanent window in orderthat the trapped air space shall not be too great. This object has beenfrustrated to a large degree because it has been necessary to include ineach storm window frame, either a handle which extends from the front ofthe window or a recessed portion in order to enable the Window to beconveniently raised and lowered. The recessed portions frequentlyrequire a thickening of the strip 11. The handles nited States Patent Qattached to the surface of the strip 11 require that the various sashesbe spaced from each other in order to allow for the passage of thehandle as the windows are raised and lowered past each other.

Thus, in a double, triple or even quadruple track storm windowconstruction, the overall thickness of the storm window construction isvastly increased by the inclusion of handles or other means to permitthe raising and lowering of the window. The enlargement of the stormwindow construction thereby defeats, to a degree, the desired insulatingproperties and in addition, makes for a bulky and unwieldy storm windowconstruction where multiple tracks are used. Also, the storm window mustbe spaced away from the primary window in order to allow for the passageof the handle as the storm window is raised and lowered.

The foregoing construction is conventional. My invention resides in thecombination of this construction with the elements hereinafter setforth. In the bottom channel 13 a tab or handle 17 is positioned. Thistab 17 has an aperture near the top which aperture is higher than itscenter of gravity so that when the tab 17 is suspended from thisaperture, its lower end 19 will gravitationally drop down. The tab' 17is mounted in the channel 13 on a pin 20 which is inserted into passages21 in the strip 11 and frictionally engaged therewith. The upper portionof the tab 17 at one corner 22 is rounded so that the pivoting of thetab will not engage it with the roof 23 or top of the channel 13. Theopposite corner 24 of the tab is higher so that when the tab pivotsdownwardly it will engage the roof 23 of the channel 13 and maintain thetab with its lower portion 19 substantially horizontal extending to oneside of a vertical line passing through the mounting hole 18. Thus,force brought to bear on the surface 25 of the tab will not cause thetab to pivot further and will enable the window to be pulled downwardly.The bottom surface 26 of the tab is rounded so that as the window islowered and the tab 17, as normally disposed, comes in contact with thesill 27, the tab will slide along the surface of the sill and will bemoved upwardly into the channel 13.

Although the tabs may be used singly as a disappearing handle for aidingthe lowering of the window, it is desirable to use them in pairs asshown in Figures 1 and 2. When the window is raised, by reason of thetabs 17 being eccentrically balanced, they drop down below the channel13 and extend out of the channel, as shown in Figure 1, being maintainedin that position by the engagement of the corner 24 with the roof 23 ofthe channel 13. When it is desired to lower the window, force applied tothe surface 25 of each of the tabs draws the sash downwardly and whenthe window is pressed down to the sill 27, the curved surface 26 of thetab 17 pivots the tab to a position wholly within the channel as shownin Figure 3.

This construction provides handles for multiple track storm windowswhich do not extend from the front or back of such windows and enablesthe plurality of windows to be spaced very close to each other andenables screens likewise to be spaced very close to each other andpermits the entire window construction to be placed very close to theprimary window of the house to which the storm window construction isapplied. When each window section or sash is raised, the handles forlowering automatically appear and they disappear when their use is nolonger required. The insulation of such closely spaced multiple trackstorm windows is vastly enhanced by reason of the minimization of theenclosed air space between the various layers of windows. The estheticappeal of windows with this type of construction is also improved, andthe compactness of the entire window as semblage is also improved.

The foregoing description is merely intended to illustrate an embodimentof theinvention. The component parts have been shown and described. Theyeach may have substitutes which may perform a substantially similarfunction; such substitutes may be known as proper substitutes for thesaid components and may have actually been known or invented before thepresent invention; these substitutes are contemplated as being withinthe scope of the appended claim, although they are not specificallycatalogued herein.

I claim:

In a storm window, vertically slidably disposed within a window framehaving a sill, and wherein the storm window comprises a bottom Windowsill engageable strip having a channel extending lengthwise and openingthrough the bottom thereof, a pivot pin secured in said strip andextending transversely thereof, the axis of said pivot pin beingdisposed a predetermined distance from the bottom wall of said channel,and a handle for moving said storm window vertically within the windowframe, said handle comprising an elongated tab having a pivot pinreceiving aperture therein adjacent one end thereof, the tab beingdefined by opposite parallel side walls, first and second straight edgesat the opposite sides of said aperture and converging in a downwarddirection away from the aperture, the said edges respectively merginginto convex and concave edges extending in a general direction away fromsaid first edge and defining with portions of said side walls, a convexwindow sill engaging surface and a concave finger engageable surface,said one end of the tab being in obtuse angular relation to said firststraight edge andin acute angular relation to said second straight edge,said tab having first and second rounded corner portions at thejunctures of the first and second straight edges with said one end ofthe tab, the high point of said first rounded portion being spaced fromthe axis of said aperture a distance no greater than the aforementionedpredetermined distance and the center of gravity of said tab being sodisposed that when the tab is free of said window sill, the high pointof the second rounded portion will engage the bottom wall of saidchannel and upon lowering of the storm window toward said sill, saidconvex surface will engage the sill and the tab will be swung about thepivot pin in a clockwise direction to a position within said channel.
